What is to "re-zip"?  You have a .zip file that contains a single file in
your work tree, and the index and the tree objects record that single file
deflated?  When you "check out" from the index, you run smudge to create a
new .zip file with that single file?

Are you recreating the .zip file in the filter in such a way that a file
with the same contents results in byte-to-byte identical .zip file?
Otherwise as far as git is concerned you have changed the file in the work
tree.
